You should also look at the new Community Care Act which was introduced in 1991 ish, with it's empahisis on closing down the large psychiatric hospitals and placing those in need of assistance in the community. this caused the birth and evolution of many community care providers, such as penumbera, the richmond fellowship, name but a few. the large institutions were no longer seen as the best place to deliver person centred care. The funding for these places comes from social work departments. So you can imagine how difficult it can be at times for people to have real choice control and empowerment in their lives, going from being controlled by hospitals to now being restriained financially by funders. The emphasis now would be to provide individuals with high care needs with "individual care packages" with them living in mainstream tenancies, but with a small core of workers supporting them in their own homes. this is expensive, but in my opinion far more "normal" than group living. It should be about what the "person" wants, not what the system can afford. Hope I haven't confused you, and good luck with the essay.
